To all 'icfwm' it may concern." f Be it known that i, Joris A.

needle may be quickly end easilypositioned with respect to the groovesof the particular type of disk to be played without moving the tone erinand without displacing f the sound box bodily with respect to said arm.Another object of the invention is to multe it possible to secure suchadjustment without modifying eppreciably the usuel form ot' tone erm andby making the adjusting devices between thelatter and the sound box ofsimple and inexpensive character. Still another object of the inventionis to permit an adjustment of the che ucter described without displacingthe needle itseit through en appreciable distance, the movement oit' thesound box'with respect to tie. tone erm telting place i'ibout an exiswhich is nearly coincident with the exis ot' the needle. A'iurtherobject is to improve the construction of tone :irins for griipliophonesby providing e simple and eii'eetivc pivotal joint therein whereby theouter end of the erm with thel sound box may be readily swung in uvertical plane when the needle is lifted ytroni therecord.

Eig. Il is :i view in side elevation showing the sound box illustratedin Figs. l und 2.

Ellie improved tone erm comprises generelly e main section a formed asan elbow and edepted to have pivotal engagement with any suitablesupporting devices, indilill() cated generally at 2', and a secondsection like, by forming the inner end et the section a withhemispherical bearing surfaces which rest snugly within the mouth ottheelbow section a and conform to thecurvature thereof. lf desired,provision may also be made, 1n the form ot a springlateh o7 carried onthe upper tace of the elbow a' and. adapted to co-act with a fixed nosec3 ,formed integral with or mounted on the upper face of the secondsection o ot the tone arm,'or maintaining this last named section inelevated position with respect to the elbow when the sound box andneedle are lifted from the record. lhe engagement of the latch ci withthe nose al", is, ot course, yielding, and the engagement and diserrgagement therebetween eii'ected readily by pressure on the secondsection c' of the arm.

The outer section a of the tone arm may be :formed either in a singlepiece or may be made up of a plurality of sections as illus trated inthe accompanying` drawings. For instance, there is indicate as at c, ashort removable section intended to be eng-aged with the straightsection c in any suitable l manner, 21S through a bayonet joint, shownat f. This short section e has its inouthgin clined generally downward,say, at an angle of abouto, and is formed on its upper surface at apoint substantially co-incident with the axis of the downwardlyextending pon tion referred to, with a recess e' in a knob e2, for apurpose which will appear later.

The improved sound bon g, in the preferred frm, has its rear wall formedwith an ,opening y and a generally circular flanged mouth g2 of suchoutline and dimensions as to receive snugly the mouth of the straightsection o olf the tone arm. The rear wall of the sound box g and thecylindrical mouth g2 thereon are preferably formed with a continuousshoulder g3 against Awhich the lip of the section. c rests when Athetone arm and sound boX are in their normal relationship. The rear wall.oi: the sound bon g is also formed adjacent periphery and preferably ata point substantie" di cally opposite the needle It, i, i rearwardlyextendingI bracket it through which passes a thumb screwv c", the pointof which is preferably tapered and rests in Athe recess c of the bearingc2 on the short section c.`

From this description it will be evident that when the thumb screw c' isset up lthe sound box g will be drawn bodily upward so 'that the lip ofthe short section e will loe locked in frictional engagement with theshoulder Saga 1 y movement. .ln realisncipal ebiects oi the applicantlsit is desirable that the thumb screw iouldhave its axis as nearly co-inc i the asis ot the needle o as poswith at all events,I have its axiswith asis off the downwardly extend nouth oll the section a. of the tonearm, that is', in the illustrated embodiment, coincident with the artisof the downwardly extendingmonth oit 'the short section e. ln this 'waythe sound bon may he rotated bod l siiipport allor/ded by the theposition shown in @les with respect thereto, As has been en plaine@ e,non the sound bei; is in the position .in in Figs. l and l?, 'the needlewill reproduce vibrations caused. by irregularities in depth ol a grooveoi' truly spiral form, while, when the sound een is in the the needlewill larities scope ofthe appended. claims not de y in'vtnition i l. lna talking machine, the combination oi a tone arm including a downwardlyin clincd section detachably secured to the end thereoi", a sound. boxprovided with a lip'to receive the mouth of 'the inclined section,
